To all whom it may 00mm;- 7

Be it known that we, HAROLD E. AUSTIN, of Louisv lle, in the county of Jefferson,

State of Kentucky, andflJEssn G. Coon, of

Jefl'ersonville, in the county of; Clark, State of Indiana, both citizens of the United States, have invented certain new and useful Improvements in Arm Extensions for B01- ster Cars; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in-the art to which it appertains to make and use the same.

This invention rel-ates to an improvement in bolster arms for tram cars employed in connection with wood impregnating cylinders. Cars of this type consist of a bolster or sill having the ends thereof curved slightly upward, and attached to these projecting ends is a curved bail-for holding the timber on the car during the treatment of the timber in the cylinder. It has been found difficult to pile the car as fully as the bail will permit, especially on round pieces such as poles and piling, and to overcome this objection, extension arms have been provided which are removably attached to the projecting ends of the bolster arm. \Vith these extension arms it is possible to load the car with the piling or poles until the load is rounded up and of a height just suflicient for the bail to be applied over the load and attached to the bolster arm.

The invention consists of certain novel features of construction and combinations of parts, which will be hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in end elevation of a tram car showing a bolster arm with bail attached thereto and illustrating the location and manner of attaching the extension arms; and Figure 2 is a view in front elevation of an extension arm.

The tram car 10, has applied thereto a bolster arm 11, which has the ends thereof curved to suit the shape of the impregnating cylinder. The bail 12 is a. rigid rod bent to conform to the upper portion of the impregna'ting cylinder, the ends of the bail being angular-1y dispose-d and adapted to be projected through apertures in the vertically disposed portions of the bolster arm. The b il is locked n p s tion be the bo s er arm by means of pins. The foregoing structure and method of attaching the bail to the bolster arm is clearly set forth in our Patent 1,428,4741, granted September 5, 1922, and a further detailed description is believed unnecessary.

"The extension arms 13, 13 are constructed of metal and slightly curved to conform to the ends of the bolster arm'l l and bail-12.

The extension arms 13 are provided'with right angularfianges 14, producing a. chanextend over the ends of the bolster arms engaging the outer faces or surfaces of the arm 11 for holding the extension arms 13 in place, and causing the upper portions of the arms 13 to engage the inner surface of the bail 12 and the flanges 1 1- to embrace the sides thereof.

In loading a tram car with lumber, one of the extension arms 13 is applied to an end of the bolster arm 11, and on the opposite side from the side the timber is being loaded on the car. The car is then loaded with timber, poles or piling, against the far side of the car, causing the poles or pilin to be laid against the extension arm 13 which has been applied to the bolster arm 11, in such a manner as to counterbalance the thrust of the lumber, poles or piling against the upper portion of the extension arm 13. After the car has been loaded to a certain degree. then the other extension arm 13 is applied to the bolster arm on the near side of the car, and then the loading is continued until the load is rounded up just sufliciently to permit of the application of the bail 1.2. I

The cost of treating a quantity of lumber is the same regardless of the amount which is actually loaded on the cars, and the advantage of these extension arms 13 affords a means for enlarging the size of the load without increasing the cost of operation. F r hermo e, p actically halt of t e car may be loaded, when an extension arm is applied to the far side of the car before it is necessary to apply the other extension arm, and eliminating the necessity of lifting the timber, poles or piling for the entire load over the top of the near side extension arm.

Of course, under some circumstances, where the cars are loaded by cranes, it may be more advantageous to have the extension arms rigidly attached to the bolster arm, but under ordinary circumstances it is preferable to have the extension arms capable of being removed. i

We claim as our invention:

1. A timber car for wood impregnating cylinders, including a bolster arm, and removable extension arms on the bolster arm so arranged and constructed that the timber loaded on the car will bear against the lower portion of the extension arms and form a resistance to counterbalance the thrust of the timber against the upper portion of the extension arms.

2. A timber car, including a bolster arm having curved ends, a bail for engaging the ends of the bolster arm, and extension arms carried by the bolster arm and adapted to lie adjacent the adjoining ends of the bolster arm and bail.

3. A timber car, including a bolster arm having curved ends, a bail for engaging the ends of the bolster arm, extension arms carried by the bolster arm and lying adjacent the inner surfaces of the ends of the bolster arm and bail, and flanges on the extension arms for embracing the sides of the bolster arm and bail.

In testimony whereof we have signed this specification.
